Following the 2026 Q1 product release and migration to a new development and distribution system, the mapping team has re-issued earlier map products. Some fire maps experienced data inconsistencies during migration; the issues have been addressed and now affected maps are available. This update improves consistency and problematic fire maps are accessible through the Burn Severity Viewer and Direct Download | Burn Severity Portal.  Since April 7th, the following have been made available: 

• Monitoring Trends in Burn Severity (MTBS) project data have been released for 221 fires from multiple fire seasons. The total number of mapped products released by the program is now 30,611. 
• The Burned Area Emergency Response (BAER) project has released fire maps for 5 fires. 
• The National Park Service (NPS) project has released 30 fire datasets from previous seasons. 
• The Provisional Initial Assessment (PIA) project has released data for 2 fires from 2026 on the Burn Severity Portal Viewer. 
• The Rapid Assessment of Vegetation Condition After Wildfire (RAVG) project has released 43 fire mapping datasets.
